JDMSPEED Universal Inline High-Pressure Fuel Pump 12V — Brass/Steel, Adjustable 135 L/hr (3 bar)

JDMSPEED's Universal Inline High-Pressure Fuel Pump is a 12V external gasoline pump designed to replace several Bosch-style part numbers and deliver a steady high-flow supply for EFI systems up to roughly 250 bhp.

This compact inline unit is built from brass and steel alloys, finished with an anodized and painted surface for corrosion resistance, and includes fittings and gaskets to simplify installation. It suits turbo and naturally aspirated gasoline injection applications where an external pump is preferred or required. The pump offers adjustable pressure capability, a robust flow rate, and compatibility with many Bosch interchange numbers commonly found on aftermarket and OEM systems.

How much flow and pressure can I expect from this pump?

The pump delivers a measured flow around 135 liters per hour at roughly 3 bar (about 45 psi), and its maximum rated pressure is about 8.5 bar (125 psi). A built-in 1/8" NPT port accepts a gauge so you can tune the outlet pressure from 0 to the pump's maximum.

• Flow: ~135 L/hr (approx. 35 gal/hr) at 3 bar
• Max pressure: ≈8.5 bar / 125 psi
• Gauge ports: 1-3/4" (45mm) and 1/8" NPT for pressure monitoring
• Adjustable output via included gauge port hardware

What fittings and hardware come with the pump and how does it connect?

The package includes the external pump plus a set of rubber covers, electrical terminals, gaskets, and nuts to help with common installations. Inlet and outlet use push-on hose fittings sized to fit typical fuel line diameters, while electrical termination uses supplied terminals.

• Included: pump, 2 rubber connection covers, 2 terminals, large/small gaskets, large/small nuts
• Inlet: 1/2" (12mm) push-on hose
• Outlet: 1/4" (8mm) push-on hose
• Electrical: 12V supply with included terminals (no wiring instructions)

Will this pump fit my vehicle or replace my existing unit?

This is a universal external inline pump that matches many Bosch-style part numbers, so it can replace a range of OEM and aftermarket pumps. Some adaptation may be required—mounting brackets, wiring, or hose adapters are sometimes needed depending on your application.

• Interchangeable with multiple Bosch part numbers including 0580464070 and related codes
• External mounting—no in-tank installation necessary
• Suitable for turbo and non-turbo gasoline injection systems up to ~250 bhp
• Installation may require mechanical skill and extra fittings (instructions not included)

Who is this for: JDMSPEED's inline high-pressure pump is intended for enthusiasts, tuners, and mechanics who need a compact, serviceable external fuel pump for upgraded fuel delivery or to replace worn Bosch-style units. It's well suited to street and track builds that demand reliable high-flow gasoline delivery, provided installers are comfortable adapting hoses, wiring, and mounting hardware when required.
